Battery overheating and fan operating loudly

Hello, I produced the EtreCheck report, could someone please advise me what steps to take to improve performance? My mac gets barely 2 hours on battery and it runs the fan quite often. While charging it's often too hot to the touch. Help!

I'm running Monterey.

Your hard drive is full. On modern versions of macOS, the operating system handles all storage issues. You can't actually delete files. All you can do is ask the operating system to delete files and it will do it when it's good and ready. But once you start to run low, then the operating system starting doing lots of extra work to keep you from running completely out of free storage.


Plus, you've been using some rendering software that has exhausted your RAM and gone into swap space, making the storage management tasks do even more work.


You need to archive and/or delete some files. EtreCheckPro has a built-in Storage management tool that will show you where your storage is being used. It will try to dissuade you from going into dangerous areas.

GACK-- your disk is FULL!


That is why the Etrecheck run is so slow and you disk Write time is pathetic.


Performance:

  System Load: 7.11 (1 min ago) 6.74 (5 min ago) 8.96 (15 min ago)

  Nominal I/O usage: 9.20 MB/s

  File system: 37.32 seconds

>Write speed: 699 MB/s. -- This should be comparable to read speed, unless you disk is choked with data

  Read speed: 2784 MB/s


 Size: 499.96 GB

>    Free: 21.84 GB

      Available: 25.79 GB


one App can use more Swap file usage than that, and completely fill all the open space and crash you Mac badly.

You need to make MUCH more space avaliable on your boot drive.


That may mean connecting an external drive. Most users are unable to quickly make substantial amounts of space available and keep it available.

By far the easiest way to cause poor performance, instability, overheating and crashing is to install ANY third-party speeder-uppers, Cleaners, Optimizers, or Virus scanners, Bit Torrent, or a VPN that you installed yourself.


you appear to be running Trusteer.

remove that junk right away, and NEVER re-install.


you are also running FAR too many third-party file-syncers.


 File providers:

    [Loaded] Dropbox - /Applications/Dropbox.app

    [Loaded] Google Drive - /Applications/Google Drive.app


  Share services:

    [Loaded] Dropbox Transfer - /Applications/Dropbox.app

    [Loaded] OneNote - /Applications/Microsoft OneNote.app


Third-party file Sync-ers such as DropBox, BackBlaze, OneDrive, or GoogleDrive can ruin performance, and use overheating but are not inherently dangerous.


They were Quickly ported from that other Operating System, and were never re-written to take advantage of the MacOS ‘File System Event Store’.  The typical brute-force search they use takes all afternoon for one pass. That relentless searching is a completely un-necessary waste of resources.


Synch and Backup programs like iCloud Drive and Time Machine that DO use the MacOS File System Event Store can find changes really quickly and be done with their work and suspend themselves. Time machine can run backups Hourly, while all those others are still beating on the file system for the first pass, four hours later. By the time those others have finished one pass, they need to start again.

Trusteer Rapport is a virus scanner. Made by IBM and pushed HARD by online banking providers.


NO such software is REQUIRED for online banking or any other activity on a modern Mac.


Uninstalling Rapport on Mac OS X


always un-install such stuff using the software-maker's un-installer, which I have linked above. Third-party site's un-installers may install malware instead. NEVER use a generic Un_installer, they are JUNK.
